Thanks for all the replies, guys! Except that deal has ended now, so I decided to talk to an expert on motherboards and got his take. He told me that the MSI Z77MA-G43 is not a very good quality board, and I agree, since it is only a MicroATX and does not have many slots of any sort. So I have made up my mind to buy the ASUS P8Z77-v, Antec 300 case, ASUS DVD burner, 8gb Corsair Vengeance 1600, Antec 620W PSU, and with a few magic promo-codes that Newegg emailed me, I can get it all for around $300. I will buy the i5 later if it ever goes on sale or just ask for it for Christmas. You know parents can't resist buying their kids $230 worth of high-tech hardware.
So yes, definitely the -3570K!!
